This cartoon, floating around on Facebook and elsewhere, makes me think about how we offer education to children.
What does giving the smallest child here a second box do for or to that child? What does the group gain when all three kids can see over the wall?
This seems true to me on the level of the individual as well as on the level of the community. Some schools, some communities need more so their children can have access, but also so they can contribute their talents to society.
When this comes to global education, we can see it as an unnecessary luxury for students in poor districts to study multiple languages, learn about climate science, and travel abroad (or art and music, for that matter). Or we can see it as a form of justice from which we all benefit.
